1. Field of the Invention
This disclosure relates generally to vehicles and systems for collecting and removing trash in commercial and residential community settings and more particularly to a system and trash receptacle for intermittently compacting trash deposited within the trash receptacle to reduce the frequency of trash receptacle emptying required.
2. Description of Related Art
In commercial and residential community settings, large receptacles or bins are provided at strategic locations for individual depositing of trash into one or more trash receptacles. One or more lids are typically pivotally openable for trash to be deposited into the receptacle and periodically, a large waste collection vehicle is scheduled to visit each of the trash receptacles and by interengagement with large forwardly extending forks, temporary engagement with each trash receptacle to lift it and invert it over the open top of the truck cargo bed of the vehicle to empty trash from the trash receptacle and then to replace it on the ground for continued use.
The trash collection service for this routine scheduled emptying of the trash receptacles constitutes a significant expenditure for the commercial establishment or residential community and is typically billed on a per-visit basis. However, many times these trash receptacles are less than full and the emptying schedule is excessive in that the trash receptacles could easily be filled with additional trash before emptying occurs.
Moreover, trash which is typically loosely thrown into these trash receptacles accelerates the appearance of trash receptacle fullness whereas, if somehow compacted or otherwise reduced in overall volume, the trash receptacle could easily handle significantly increased amounts of compacted trash before the receptacle would be required to be emptied.
A number of prior art vehicles, systems and receptacles are known in prior art which attempt to address this issue of increasing the efficiency and cost of trash removal as follows:
U.S. Pat. No. 3,691,967 to Mettetal, Jr. discloses a mobile apparatus for compacting refused. It is the primary object of the '967 patent to provide a mobile refuse compacting vehicle for compacting refused contained in separately located receptacles which will extend the time interval between the unloading of such receptacles. LaBarbera teaches a mobile trash pulverizer in U.S. Pat. No. 6,739,535. As is shown in
A device for compacting waste in containers is disclosed in newly-issued U.S. Pat. No. 7,100,500 to Soler as shown in
Shinjo, et al. teach a solid substance crushing vehicle which is able to move to a collection center in U.S. Pat. No. 5,927,626 and a waste recycling processing vehicle is described in U.S. Pat. No. 5,842,652 to Warsing, et al.
A compactor comprising a rotating auger for breaking waste material is disclosed in U.S. Pat. No. 5,575,201 to Fenner, et al. and Faccia teaches a combined shredding and mixing truck in U.S. Pat. Nos. 5,465,914 and 6,983,902.
Waste compaction apparatus with a screw conveyor for waste material compacting is taught by Hamilton in U.S. Pat. No. 6,247,662 and the method and apparatus is disclosed in U.S. Pat. No. 6,505,550. The front page of a refuse collecting and disposal handling vehicle teaching two vehicles working in tandem is taught by Talamantez in U.S. Pat. No. 6,305,625.
My previous U.S. Pat. No. 7,434,507 teaches a unique system and trash receptacle as a separate service offering for compacting trash deposited within the trash receptacle periodically in between times of trash removal by a commercial trash collection operation. A compaction vehicle periodically visits each trash receptacle in the system to operate a power unit which effects compaction of the trash collected within the trash receptacle and, at a point when the operator of the compaction vehicle determines that the compacted trash has adequately filled the receptacle, a radio signal is activated to advise the waste collection company that the trash receptacle is ready for emptying.
The present disclosure teaches an improved system and trash receptacle for periodically compacting trash deposited into the receptacle in between times of trash removal from the receptacle by a commercial trash collection operation. An improved compaction vehicle periodically visits each trash receptacle in the system and, after proper engagement with the internal moveable compaction ram, a power unit attached to the front of the vehicle will actuate the compaction ram to effect compaction of the trash then collected within the receptacle. Trash compaction by this new system more efficiently effects trash compaction for extended time periods between each trash receptacle emptying.
The foregoing examples of the related art and limitations related therewith are intended to be illustrative and not exclusive. Other limitations of the related art will become apparent to those skilled in the art upon a reading of the specification and a study of the drawings.
This disclosure is directed to a system for compacting trash within a trash receptacle including a trash receptacle having upstanding front, side and back panels, a closed bottom, and a lid. A compaction ram sized in width and length similar to that of the front panel and positioned within the receptacle against the front panel and is separate and movably held by spaced parallel upper and lower slide rails. A drivable satellite vehicle having power unit temporarily connectable to the compaction ram drives the compaction ram into the interior volume of the trash receptacle which compacts the trash within the receptacle at the time to minimize the frequency of receptacle emptyings required.
It is therefore an object of this disclosure to provide a system for compacting trash within a trash receptacle of the system at least once in between scheduled periods of entirely emptying of the trash receptacle.
Yet another object of this invention is to provide a means for compacting loose trash deposited within a uniquely configured trash receptacle to reduce the cost and frequency of emptying of the trash receptacle by use of a commercial trash collection vehicle.
Yet another object of this invention is to provide a trash receptacle which is adapted for compacting loose trash deposited therewithin by a compaction vehicle equipped with a power unit for temporary engagement with a movable compaction ram within the trash receptacle to effect compaction of the loose trash collected within the trash receptacle.
The following embodiments and aspects thereof are described and illustrated in conjunction with systems, tools and methods which are meant to be exemplary and illustrative and not limiting in scope. In various embodiments one or more of the above-described problems have been reduced or eliminated while other embodiments are directed to other improvements. In addition to the exemplary aspects and embodiments described above, further aspects and embodiments will become apparent by reference of the drawings and by study of the following descriptions.
Exemplary embodiments are illustrated in reference figures of the drawings. It is intended that the embodiments and figures disclosed herein are to be considered to illustrative rather than limiting.
Referring now to the drawings, and particularly to
A separate moveable compaction ram 16 is positioned within the interior volume of the receptacle 18 and, in the at rest position shown in
Attached to one face of the compaction ram 16 are three spaced ram connectors 24, each of which define an upwardly facing U-shaped hook. Each of these ram connectors 24 is oriented to align with the corresponding actuator opening 22 as best seen in
As will be more fully described below with reference to
When the lid 40 is in the closed position as best seen in
Two coil springs 110 and 116 are positioned over the lid hook link 42. The main spring 110 is held in compression between spring stop bracket 112 attached to the front panel 20 and a spring stop pin 114 rigidly connected transversely through the hook link 42. Spring 116 at its lower end bears against an edge of foot 94 while the upper end thereof is restrained by spring pin 120.
The lid 40 includes two spaced apart lid hooks 90 which align themselves into a notch formed into the lid latch 44 as best seen in
As seen in

As seen in
It is noted that both of the engagements with the trash receptacle assembly 12, i.e., the locking pins support 56 with the lifting bracket 26 and the connector bars 60 and 64 against the ram connectors 24 of the compaction ram 16 are both required to maintain stable positioning of the trash receptacle assembly 12 during compaction. That is the trash receptacle 18 is restrained from movement while the compaction ram 16 is being moved fore and aft within the receptacle 18 to effect compaction of the trash T and then a retraction of the compaction ram 16 back to its at rest position against the inner surface of the front panel 20. Without the opposing forces being generated, the system would be unstable.
